Effect of Bamboo Powder Parameters on Mechanical Properties of Bamboo-plastic Composites
In order to determine the best bamboo fiber parameters of bamboo-plastic composites,further improve the mechanical properties of bamboo plastic composites,bamboo fiber(BF)was used as the main raw material,and biodegradable polypropylene carbonate(PPC)was used as the resin monomer to prepare BF/PPC composite by hot pressing process.The effects of BF particle size and the amount of BF on the tensile,bending and impact properties of BF/PPC composites were studied by single factor test.The results showed that under the hot pressing process conditions of 170℃,1.9 MPa and 10 min,the mechanical properties of the composite increased first and then decreased with the decrease of bamboo powder particle size,and reached the best when D80 bamboo powder was added.At the same time,its mechanical properties also showed a similar change pattern with the increase of bamboo powder addition,and the optimal mechanical properties were achieved when the bamboo powder addition was 40%.In this experiment,when D80 bamboo powder was added and the amount of bamboo powder added was 40%,the BF/PPC composite material exhibited the best mechanical performance.
